Parameters (see above)
Remarks
3D cells take on the averaged values within a search radius, weighted inversely by distance.
Weighting can be controlled using the power and slope properties;
weighting = 1 / (distance^wtpower + 1/slope) where distance is in
units of grid cells (X dimenstion). Default is 0.0,
If the blanking distance is set, all cells whose center point is not within the blanking distance of
at least one data point are set to dummy.
REG Parameters:
X0, Y0, Z0, DX, DY, DZ: Voxel origin, and cell sizes (required)
WT_POWER (default=2), WT_SLOPE (default=1) Weighting function parameters
SEARCH_RADIUS: Distance weighting limit (default = 4 * CUBE_ROOT(DX*DY*DZ))
BLANKING_DISTANCE: Dummy values farther from data than this distance. (default = 4 * CUBE_ROOT(DX*DY*DZ))
LOG: Apply log transform to input data before gridding (0:No (default), 1:Yes)?
LOG_BASE: One of <define>VV_LOG_BASE_10</define> (default) or <define>VV_LOG_BASE_E</define>
LOG_NEGATIVE: One of <define>VV_LOG_NEGATIVE_NO</define> (default) or <define>VV_LOG_NEGATIVE_YES</define>
